This curriculum guide is the third in a series of general science guides modified from the New York State Experimental Syllabus, Science 7-8-9 to meet the needs of students whose interests are in areas other than science. The guide is laboratory-oriented and contains many open ended, pupil activities in five activity blocks: orientation, forces at…

The Industrial Arts Interaction Analysis System was used to study teacher-student behavior in junior high school industrial arts classes. Twenty industrial arts teachers were observed on three different occasions and the interaction between the teacher and students was recorded by two independent observers. The findings indicated that there was a…

IN-ED is a monthly publication devoted to innovative educational ideas in higher education. In this issue, the facilities and equipment used in a completely self-paced life science laboratory at the University of Texas of the Permian Basin are described. Also discussed are the instructional methods used. (MH)

Designed to assist the teacher in introducing a unit on research and experimentation into his/her industrial arts program, this manual provides information for adoption to both classroom instruction and laboratory activities, and a student workbook. The instructor's section includes (1) What is Research? (2) Importance of Research and…

Investigates whether chemistry laboratory skills are commonly developed in secondary schools and whether college professors and high school teachers agree that students still demonstrate these skills in first-term college chemistry labs. One hundred and four chemistry teachers and 298 college professors participated in this study. (HM)

Described is a sampling board that has been used in an introductory general ecology course that is inexpensive to construct and that effectively illustrates the principles of vegetation sampling. (Author/BB)

This is a course required of all sophomores at the Colorado School of Mines. It introduces students to the principles of measurement theory at a higher level than is common in an elementary physics lab. The subjects of error analysis, graphing, least-squares analysis, experimental design, measuring instruments, and report writing are covered.…

Describes a chemistry course designed for the general student at Pampa Senior High School, Pampa, Texas. It presents the fundamental concepts in chemistry in a nonmathematical context; contains many options in the form of minicourses; and permits the student to pace himself. (HM)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)

Brief suggestions for laboratory and classroom instruction in various chemistry topics are provided. (CP)

This laboratory exercise for junior or senior high school students forms a basis for expansion of concepts, offers opportunities for analytical thinking, and presents possibilities for independent thinking. (BB)

Suggests ways to avoid some of the problems students have learning the principles of organometallic chemistry. Provides a description of an experiment used in a third-year college chemistry laboratory on molybdenum. (TW)

With an aquarium and a few tools, a simple apparatus to quantitatively illustrate absorption rates of light passing through fresh, salt, and other waters (such as distilled water) can be constructed. Students learn that extinction rates are different and that the intensity/depth relationship is exponential. (DH)

Describes a physical chemistry experiment that uses Fourier transform (FTIR) spectrometers and microcomputers as a way of introducing students to the spectral storage and manipulation techniques associated with digitized data. It can be used to illustrate FTIR spectroscopy, simple kinetics, inorganic mechanisms, and Beer's Law. (TW)

Describes a process for producing terminal or internal alkynes from ketones. Recommends using the experiment to aid in understanding acid-base strength, enolate anion chemistry, reaction at carbon versus oxygen, use of polar aprotic solvents, and elimination and nucleophilic substitution reactions.
